POLICE are appealing for witnesses after a teenage girl was pushed up against a fence and sexually assaulted in Chertsey.

The 17-year-old was walking along Staines Lane near the M3 bridge between 3am and 5am on Saturday March 2 when she was approached by three men.

One of the men started walking with her before shoving her into the fence and assaulting her, It happened on the approach to the concrete culvert running under the motorway bridge.

The attacker was described as a tall, broadly built, white man with short dark hair and stubble, aged between mid-20s and early 30s, with pale skin and strong cheek bones, and a large old scar on the right side of his neck.

He was wearing a plain white top with the Ralph Lauren horse logo, jeans with no belt and trainers, and had tattoos on fingers on his left hand.

Detective Sergeant Steph Best said: "I would urge people to think back to the night of Friday March 1 and the early hours of Saturday March 2.

"Did you see a man matching the suspect's description out in the town or when you were making your way home in the early hours?

"I would also urge the two men who were with the suspect to come forward. There is no suggestion they were involved in the assault.

"We need them to do the right thing and let us know the identity of their friend or at least tell their side of the story.”

Anyone with information can contact Surrey Police on 101 quoting reference RM/13/1125 or by ringing Crimestoppers in confidence on 0800 555 111.
